This instrument is not authorized for use in contact with the human body or for use as a 
component in a life-support device or system. 
Do not touch live circuits 
Instrument covers must not be removed by operating personnel. Component replacement and 
internal adjustments must be made by qualified service-trained maintenance personnel who 
are aware of the hazards involved when the instrument's covers and shields are removed. 
Under certain conditions, even with the power cord removed, dangerous voltages may exist 
when the covers are removed. To avoid injuries, always disconnect the power cord from the 
instrument, disconnect all other connections (for example, test leads, computer interface 
cables, etc.), discharge all circuits, and verify there are no hazardous voltages present on any 
conductors by measurements with a properly-operating voltage-sensing device before touching 
any internal parts. Verify the voltage-sensing device is working properly before and after 
making the measurements by testing with known-operating voltage sources and test for both 
DC and AC voltages. Do not attempt any service or adjustment unless another person capable 
of rendering first aid and resuscitation is present. 
Do not insert any object into an instrument's ventilation openings or other openings.
